Thomas & Betts RC10-14 – Frequently Asked Questions

1) What wire size does the Thomas & Betts RC10-14 ring terminal crimp onto?
The RC10-14 is sized for 12-10 AWG stranded copper conductor and lands on a 1/4 inch stud. The yellow nylon body is the standard color code for the 12-10 range, so on a panel where you are also running red (22-16) and blue (16-14) terminals, yellow tells the next electrician what gauge went under that lug without pulling it apart. Insulation OD up to 0.21 inch will pass through the sleeve, which covers ordinary THHN and machine tool wire in that range.
2) Is the Thomas & Betts RC10-14 ring terminal rated for 600V?
Rated 600V and 105 degrees C, and it is UL and CSA certified. The nylon sleeve carries a UL 94 V-2 flammability rating. That combination covers ordinary commercial and industrial control work, including inside enclosures that run warm. If your application is a high temperature furnace lead or anything above 105 C, this is not the terminal for it.
3) What crimp tool do I need for Thomas & Betts RC series insulated ring terminals?
Thomas & Betts recommends the ERG4001 for the RC series. Also listed as suitable are the WT2000, WT112M, WT145C, ERG4003 and WT145A. Insulated nylon terminals need a tool with the correct insulated-crimp nest, not a bare-terminal die: the sleeve has to be compressed along with the barrel so the bronze insulation grip closes on the jacket. That grip is what lengthens the flexing radius behind the crimp and keeps the strands from creeping out under vibration, and a wrong die defeats it.
4) Should I use a ring terminal or a fork terminal on a control panel terminal block?
A ring like the RC10-14 has to come off the stud entirely to remove the wire, since the nut and any terminals stacked above it must be taken off first. A fork (spade) slides out with the screw only backed off. Rings are what you want anywhere vibration or a code inspection is in play, because the wire cannot back out if the nut loosens, which is why motor control centers and distribution gear are typically ringed. Fork terminals are the practical choice on a dense terminal strip you expect to be re-landing often during commissioning.
5) Are these ring terminals suitable for a damp or corrosive environment?
The RC10-14 is copper with an electro tin-plated finish, which is the standard plating for general indoor commercial and industrial use and resists ordinary oxidation on the contact face. Tin over copper is not a marine or chemically aggressive plating, so for wash-down areas, coastal exteriors or corrosive process environments you want a sealed heat-shrink insulated terminal instead of a nylon barrel, since the nylon sleeve is not a moisture seal.
6) Can I use a 12-10 AWG ring terminal on an equipment grounding conductor?
Yes, equipment grounding is one of the applications the RC series is built for, and a ring is the correct style for a ground because it cannot pull off a loosened stud. Match the terminal to the ground conductor gauge: this one covers 12-10 AWG on a 1/4 inch ground stud or lug screw. For a larger bonding jumper you need a bigger barrel, and a green-coded terminal is worth using where the panel convention calls for it, since the yellow here identifies wire size rather than function.
7) How many ring terminals come in a box and do I have to buy a full carton?
RC10-14 terminals come 50 to the inner box and 250 to the outer carton, and they order in multiples of 50. For an MRO crib stocking a panel shop, the 250 carton is the practical restock unit; for a single job, the 50 box is where you start. Weight runs about 5 pounds per 1000 pieces, so a 250 carton of terminals is a little over a pound of hardware.
8) Do Thomas & Betts RC10-14 terminals meet RoHS for a spec that requires it?
RoHS compliant, which is what a submittal on institutional or federal work will usually be asking for on wiring accessories. Between that, the UL and CSA certification and the UL 94 V-2 nylon, the RC series covers the boxes a facilities spec normally checks on a terminal.
